Dielectric reluctance

As seen above, dielectric reluctance is represented as *lowercase z epsilon*. For a dielectric in a dielectric circuit to have no energy losses, the imaginary part of its dielectric reluctance is zero. This constitutes a lossless "resistance" to electric induction flux, and is therefore real, not complex. This formality is similar to Ohm's law for a resistive circuit. In dielectric circuits, a dielectric material has a "lossless" dielectric reluctance equal to: ::z_\epsilon = \frac{1}{\epsilon \epsilon_0}\frac{l}{S} Where: - l is the circuit length - S is the cross-section of the circuit element - \epsilon \epsilon_0 is the dielectric permeability ## References 1.
